What does law say about the standoff between Himachal & Delhi Police?

Himachal Pradesh Police accused Delhi Police of violating interstate arrest procedures by not informing local police before their operation to arrest three Youth Congress workers in Shimla over the AI Summit protest. While Section 45 of BNSS empowers police to arrest offenders without a warrant anywhere in India, Section 82 mandates that local police be notified and endorse the warrant.
